C/C++ Program for Finding square of the given number & greatest of the two number through MACRO FUNCTIONS IN C++

/* The following C++ program, in ANSI Standard, defines two macro function namely for squaring & finding max of the two numbers. In both the two cases the user inputs data & the macro function process the data & returns it. The purpose of MACRO function is to improve the speed of the program
by reducing the wastage of time in calling function again & again
.These function are defined by using (#) preprocessor directive . All the call statements to a macro function will be replaced by its code during compile time.*/
